DOOR-CONTROLLING DEVICE.

SPECIFICATION for ing part of Letters Patent No. 523,431, dated July 24,1894.

Application filed April 23, 1 S94 To all whom it may conoerm Be it knownthat I, JOSIAH J. KINSEY, of Rochester, in the county of Monroe andState of New York, have invented a new and useful Improvement inDoor-Controlling Devices,

which improvement is fully set forth in the. following specification andshown in the accompanying drawings.

My invention relates to doors adapted to be thrown open by self-actingdevices, the invention being adapted more particularly to be used infire houses to release horses suddenly invention relates to theconstruction, opera tion and control of said doors.

The invention is hereinafter fully described and more particularlypointed out in the claims. Referring to the drawings Figural is a frontelevation of a door with 'myimprovements attached in place. parts actingupon the door. Fig. 3 is a horizontal cross section on, the dotted line3 3 in Fig. 1, viewed as indicated by arrow. Fig. 4. is a similar crosssection of parts at ,the meet- Fig. 5 is a side elevation of a part atthe meeting edges of the door, partly vertically sectioned to show anexpanding spring. Fig. 6 is across section through a part of one hingeand associated parts taken on the dotted line 6 6 in Fig. 2, partsbeingshown in two positions by full and dotted lines. Fig. 7 is a crosssection of a part of the door casing drawn to show more fully the meansfor controlling the action of some of the parts. Fig. 8 shows more fullythe form of a friction stop for the door. Figs. 2, 4, 5, 6, 7 and 8 aredrawn to scales larger than Figs. 1 and 3.

Referring to the parts shown, A is the door held to the casing B byhinges O. The parts of the hinges secured to the door are offset asclearly shown in Fig. 6, on account of which when the doors are thrownopen they swing back leaving a clear unobstructed opening Fig. 2 is aview ofv Serial ll'o. 608,689. (No model.)

through the casing, as appears in Fig. 3, so

that when the confined horse hastens out he will not encounter any partof the door;

The two parts of the door are thrown open by means of torsional springsa a held rigidly at their lower ends to the casing. These springsaresecured to and act directly upon vertical fan levers I) held to turn inbearings a rigid with the door frame. The fan levers, which are usuallyassociated with the middle hinges of the doors, pass between the twoparts of the hinges, as shown in Fig. 6, and

are caused to bear with considerable force upon'the outer parts of thehinges by means of the action of the springs. doors are free orunbol'ted the springs turn the fan levers in their bearings and,pressing against the contiguous parts of the hinges, throw the doorswide open, as indicated.

The springs. are made with sufficient strength to throw the doors backto positions parallel with those occupied by them when closed. But sogreat a motion is frequently notnecessary, and sometimes objectionableand to regulate the distance through which the doors are thrown back Iemploy stops (1,

Fig. 7, to limit the motion of the fan levers.

These stops consist of threaded shafts held horizontally in bearings erigid with the door casing in position to be encountered at their endsby the outwardly moving fan levers. By turning these threaded stops intheir. bearings one way or. the other the motions of the fan levers maybe arrested at will; and the instant the latter encounter the stops theytemporarily cease acting upon the doors which latter continue to moveonward from inertia only.

It will be understood that the earlier the fanver is stopped as abovedescribed the hinge continues to ride outward 1 upon the brake and so isbrought to a stop on account of the friction between the parts.

The brake curves Now when the upward at its outer end so that thefriction or resistance felt by the hinge increases as the latter movesaway from the fan lever. This brake is made of yielding material as, forinstance, spring brass so as to bend slightly downward under thepressure of the hinge.

The brake g is secured to the door casing brake presses successivelyharder upon the hinge. These two brakes acting in the manner describedserve to arrest the motion of the door easily and without shock or jar,and

also hold it with reasonable firmness in place against the action ofmoderate pressures, as for instance that exerted by puds of wind, andthe like.

The doors are closed by hand against the shown, and controlled by anarmature connected with some source of electricity in a manner that iscommon.

I prefer to provide one of the doors with an adjustable edge strip Z,Figs. 3, 4 and 5, formed with a longitudinal groove m fitting over acorresponding tongue n on the main part of the door, as shown. Thisstrip meets the otherdoor as shown and its meeting edge is made concaveand the adjacent edge of the other door is made convex so as to closetightly and leave no crack between them. The stripZ is made horizontallyadjustable upon the contiguous part of the door by means of horizontalscrews 0 passing through it and threaded into the main part of the door.

Springs 19, Figs. 4 and 5, in the groove, secured to the tongue andbearing against the strip, tend to push the latter away from thecontiguous part of the door and make atight joint between the twomeeting edges of the doors; while by means of the screws the action ofthe springs may be controlled and the width of the door thus increasedor diminished atwill. For instance if the doors shrink and leave a widecrack between them the screws may be correspondingly set out and allowthe springs to push the strip outward and close the crack. On the otherhand if the edges of the doors bind too tightly from any cause thescrews may be tightened up to draw the strip nearer to the main part ofthe door.

I cover the strip with a sheet 0* of metal, as galvanized iron forinstance, as shown, partly for the purpose of protecting the thin orsharp edges of the strip at the sides of the concavity. This sheet ofmetal is socured to the strip by screws or fasteners s and extended farenough back to lap over the adjacent portion of the contiguous part ofthe door and cover the joint between said main part and the strip. Thesheet metal is free to move upon the main part of the door as the screws0 are turned, and its free edges may be plain as shown in Fig. 1 orscalloped or otherwise ornamented, as shown in Fig. 5.

That I claim as my invention isl. A door. and its casing provided withhinges, in combination with a fan lever held to turn in bearings inpositionto bear against the hinge, and anactuating spring held by thecasing and secured to the fan lever and adapted to turn the latter toopen the door, substantially as shown.

2. In combination witha door and its casing, hinges for the door, arotary fan lever bearing against the hinge, an actuating spring securedto the casing and the fan lever and adapted to turn the latter wherebythe door is opened, and an adjustable stop to control the action of thefan lever, substantially as shown and described.

3. A door and its casing with hinges to join them, in combination with arotary fan lever bearing against thehinge,an actuating spring for thefan lever secured to the casing'and serving to throw the door open, anda friction brake fcarried by the fan lever, substantially as shown anddescribed.

4:. In combination with a door and casing and hinges for the door, meansfor automatically throwing the door open and a friction brake secured tothe casin g in position to bear upon the hinge, substantially as shownand described.

5. A door casing, a door formed in two main parts meeting at the middleand adapted to swing away from eachother, and hinges for said main partsof the door, in combination with means for throwing the parts of thedoor open, one of said main parts of the door being formed with alongitudinal adjustable strip at its meeting edges adapted to be movedtoward or from the contiguous part of the door to alter the width of thelatter, substantially as and for the purpose specified.

In witness whereof I have hereunto set my hand, this 20th day of April,1894, in the pres ence of two subscribing witnesses.

JOSIAH J. KINSEY.
